Ecosystem Management - overview

Students learn about:

Ecosystems and their management

• interactions which lead to diverse ecosystems and their functioning 
• vulnerability and resilience of ecosystems 
– impacts due to natural stress 
– impacts due to human induced modifications to energy flows, nutrient cycling, and relationships between biophysical components 
• the importance of ecosystem management and protection 
– maintenance of genetic diversity 
– utility values 
– intrinsic values 
– heritage values 
– need to allow natural change to proceed 
• evaluation of traditional and contemporary management strategies. 

Case studies of ecosystems 
• Case study 1: Intertidal wetlands:
– spatial patterns and dimensions: location, altitude, latitude, size, shape and continuity 
– biophysical interactions including: 
  • the dynamics of weather and climate 
  • geomorphic and hydrologic processes such as earth movements, weathering, erosion, transport and deposition, soil formation 
  • biogeographical processes: invasion, succession, modification, resilience 
  • adjustments in response to natural stress 
– the nature and rate of change which affects ecosystem functioning 
– human impacts (both positive and negative) (human impact on Towra Point)
– traditional and contemporary management practices. ( management strategies at Towra Point Wetlands)


Case study 2: Coral Reefs
– spatial patterns and dimensions: location, altitude, latitude, size, shape and continuity 
– biophysical interactions including: (Coral Triangle) (Great Barrier Reef)
  • the dynamics of weather and climate 
  • geomorphic and hydrologic processes such as earth movements, weathering, erosion, transport and deposition, soil formation 
  • biogeographical processes: invasion, succession, modification, resilience 
  • adjustments in response to natural stress 
– the nature and rate of change which affects ecosystem functioning 
– human impacts (both positive and negative) (Coral Triangle) (Great Barrier Reef)
– traditional and contemporary management practices. (Coral Triangle) (Great Barrier Reef)
The selected ecosystems at risk could include areas such as coastal dunes, freshwater wetlands, inter-tidal wetlands, coral reefs, arid areas, alpine areas, rainforests, temperate forests. 

Students learn to:

Investigate and communicate geographically by 

• asking and addressing geographical questions such as 
– what are the reasons for the location of the Great Barrier Reef? 
– what action is appropriate for managing wetland ecosystems sustainably? 
– what will the rainforests of Kalimantan be like in the future? 

Use geographical skills and tools such as 

• calculating the gradient of a slope as a ratio 
• calculating the vertical exaggeration of a cross section describing a specific ecosystem 
• determining sight lines between two points 
• recognising features of changing pressure patterns on weather maps in order to describe characteristics of different ecosystems 
• constructing a log of events and activities to manage the development of a fieldwork activity explaining human impacts on an ecosystem at risk 
• interpreting frequency distributions and diagrams about energy flows in different ecosystems 
• constructing a precis map from an aerial photo or satellite image to describe spatial patterns of overland flow 
• using GIS to examine spatial and ecological issues relevant to the protection and management of ecosystems. 

Identify geographical methods applicable to, and useful in, the workplace such as 

• using meteorological data, satellite imagery and aerial photography 
• constructing environmental maps and compiling environmental impact reports 
• the relevance of a geographical understanding of ecosystems at risk to a particular vocation such as: managing a national park, guiding tourist groups, ecological mapping for surveyors, evaluating dune stabilisation programs preserving heritage sites.
